DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are only part of the embodiments of the present disclosure, not all embodiments. Based on embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the scope of protection of the present disclosure.

[0032] Referring to FIGS. 1-6, the present disclosure provides one technical solution: A junction box mounted to be flush with a wall surface and convenient for line repair includes a junction box body 1 and a flip cover body 2; a top surface of one part of the junction box body 1 sinks to form a step surface 3; the step surface 3 extends to an edge of the junction box body 1; the flip cover body 2 is hinged to a first end 4 of the junction box body 1; the flip cover body 2 is clamped on the junction box body 1; the flip cover body 2 is fitted to the step surface 3; the flip cover body 2 presses against a second end 5 of the junction box body 1; a top surface of the other part of the junction box body 1 is provided with a connector 6 extending towards two sides; a plurality of threading holes 7 running through the junction box body 1 are formed in a side wall of the junction box body 1; the plurality of threading holes 7 are located at the first end 4; two symmetrically disposed wire clamping plates 8 are arranged in each threading hole 7; and the wire clamping plates 8 are connected to the junction box body 1.

[0033] The junction box body 1 and the flip cover body 2 are integrated. A fixture block 9 is arranged on an inner wall of the junction box body 1; a fastener 10 is arranged on a bottom surface of the flip cover body 2; and the fastener 10 is fastened on the fixture block 9, thus improving the integrality of the junction box body 1. The fastener 10 on the flip cover body 2 is plugged into the fixture block 9, so that the flip cover body 2 can be firmly attached to the step surface 3 to cover the interior of the junction box body 1. When the fastener 10 on the flip cover body 2 is pulled off from the fixture block 9, the flip cover body 2 can be flipped to be separated from the step surface 3 to expose the interior of the junction box body 1, so that the interior condition of the junction box body 1 can be inspected without dismantling the switch or socket at the connector 6, which facilitates repair and maintenance. The fastener 10 has an elastic deformation function, so that it is convenient for the fastener 10 to be plugged into the fixture block 9 or separated from the fixture block 9 after the deformation.

[0034] A limiting boss 11 is arranged on the bottom surface of the flip cover body 2; and the limiting boss 11 presses against the inner wall of the junction box body 1 located at the first end 4 to achieve a limiting effect on a covering position of the flip cover body 2 on the step surface 3, so that the flip cover body 2 can be accurately fitted to the step surface 3 and cover the interior of the junction box body 1.

[0035] The wire clamping plates 8 are integrated with the junction box body 1, which is convenient for improving the integrality of the junction box body 1, so that there is no need to additionally mount wire clamping plates 8 during the mounting of the junction box body 1, and the junction box body 1 can have a wire clamping function to prevent cables from moving; and the wire clamping plates 8 have the characteristic of elastic deformation.

[0036] A plurality of sawteeth 12 are arranged on the wire clamping plates 8; and the sawteeth 12 on the wire clamping plates 8 located in the same threading hole 7 are oppositely disposed. The oppositely disposed sawteeth 12 clamp a cable passing through the threading hole 7 to restrain the movement of the cable, thus ensuring the mounting stability of the cable.

[0037] An end part of the flip cover body 2 facing to the second end 5 is provide with a bent end 13 that is upwards bent; a limiting rib 14 is arranged on the inner wall of the junction box body 1; and the bent end 13 presses against the limiting rib 14, so as to play a limiting role for the covering position of the flip cover body 2 at the step surface 3, so that the flip cover body 2 can be accurately fitted to the step surface 3 and cover the interior of the junction box body 1. At the same time, the bent end 13 covers the space of the junction box body 1 at the second end 5 to ensure that the internal space of the junction box body 1 cannot be seen from the second end 5 after the socket or switch has been mounted on the junction box body 1; and the beautiful mounting effect is guaranteed.

[0038] The second end 5 is provided with a guide slope 15 which has a guide effect on the flipping of the flip cover body 2 and is convenient for smooth clamping of the flip cover body 2.

[0039] The working principle is as follows: First, when the flip cover body 2 is fitted to the step surface 3, the junction box body 1 is mounted in a wall body; the top surface of the flip cover body 2 overlaps the wall surface; the connector 6 of the junction box body 1 protrudes from the wall surface; an end part of the cable is threaded into the junction box body 1 from the threading hole 7; the cable passes between the two wire clamping plates 8 in the threading hole 7; elastic deformation occurs in the wire clamping plates 8; and the sawteeth 12 on the wire clamping plates 8 firmly clamp the cable. Second, the bent end 13 is pinched and pulled; the fastener 10 falls off from the fixture block 9 under the action of an external force, and the flip cover body 2 is flipped to be separated from the step surface 3; the socket or switch is wired and mounted on the connector 6 of the junction box body 1; and the socket or switch covers the top surface of the junction box body 1. Then, the flip cover body 2 is flipped to be folded towards the step surface 3. The flip cover body 2 is in contact with the guide slope 15 when it is flipped to the second end 5. The guide slope 15 has a guide effect on the flip cover body 2, so that the flip cover body 2 presses against the second end 5. At this time, the flip cover body 2 starts to be fitted to the step surface 3; the limiting boss 11 slowly presses against the inner wall of the junction box body 1 located at the first end 4; and the bent end 13 presses against the limiting rib 14. Under the limiting action of the limiting rib 14 and the limiting boss 11, the flip cover body 2 accurately covers the junction box body 1, and the bent end 13 covers the space of the junction box body 1 at the second end 5, thus avoiding the interior of the junction box body 1 from being exposed and ensuring the beautiful mounting effect. Finally, without dismantling the switch or socket at the connector 6, the flip cover body 2 is flipped to be separated from the step surface 3, so as to expose the interior of the junction box body 1, and then the interior condition of the junction box body 1 can be inspected. Thus, it is convenient for repair and maintenance. After the repair and the maintenance are completed, the flip cover body 2 is flipped to be fitted to the step surface 3.

[0040] The above descriptions are only specific preferred implementation modes of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. For any person skilled in the art, within the technical scope disclosed by the present disclosure, equivalent substitutions or changes made according to the technical solution of the present disclosure and an inventive idea of the present disclosure shall all fall within the scope of protection of the present disclosure.
